Hi all Is the schema for menu collection correct here : https://typesense.org/docs/guide/tips-for-filtering.html#filtering-nested-array-objects ? Shouldn't ingredients.name and ingredients.concentration be arrays ?

Yes you are correct. Any field inside an

object[]

becomes an array.

And if I want to sort 2 dishes in a menu based on ingredients.name, will that work with just enabling sort:true on the ingredients.name array field ?

Sort requires a singlular field.

So if I need something like that I'll need to sort the array at index time, set a document level value to array[0] and use that for sorting. right ?

Yes, you have to pre-sort or sort in the client.
